Volume 2 Issue 1 Jan , pp. The model over-predicted grossly the trapping efficiency of all particle fractions, but it is unreliable particularly for small particles. Less effective as the cropland area drained through the vegetated area is increased. Necessary adjustments and additions add additional expense.

Water Management

Grass filters and riparian forest buffers both improve habitat diversity and provide habitat for many Nebraska wildlife species. Therefore strips collecting stormwater from distances greater than indicated above will be ineffective. Planting grass filter strips: The plants selected should be able to withstand flowing water, and both wet and dry periods. The filter strip must be designed to withstand the full range of storm events without eroding. About the article Received:

Stormwater Management - Filter Strips

In , the Nebraska Corn Growers Association provided incentives and collaborated with farmers to install 20 vegetative filter strips to demonstrate how filter strips reduce runoff of sediment and pesticides caused by rainfall. When properly designed they require large areas of land: Grass species chosen must withstand high velocity flows and irregular climate conditions. Maintenance may also include mowing, trimming, or burning the plant community, depending on specific needs of the vegetation. They are designed to filter out the sediment, organic material, nutrients, and chemicals carried in runoff water.

This conservation practice is the most frequently planted riparian buffer type in the United States. Materials and Installation Design Considerations: Specifically, they may be used in the following applications: Agricola Articles by Williams, R. Channelized flow significantly reduces the effectiveness of a filter strip because flow velocities are minimally reduced and the effects of filtration through plant stems and accumulated thatch on the ground surface are lost. Abstract Field studies were conducted in , , and to determine the effectiveness of several grasses as filter strips for reducing sediment and herbicide losses in runoff.
